Paper Abstract

A soundly based procedure is presented for the correction of the variations that occur in the baselines of spectra obtained by transmission through a thin cell containing liquid. The correction significantly improves the precision of optical constants obtained from such spectra. The method is applied to the 1036 cm-1 band of benzene.
